When a tea kettle whistles, it is because the liquid inside turns to steam and is forced by pressure through the small opening in the kettle lid. This phase change is a physical change, not a chemical one.
Tea kettles whistle when the water boils because the steam from the boiling water passes through a small opening in the kettle's spout, causing vibrations that create the whistling sound.

Rust in a tea kettle is not necessarily dangerous to your health, but it can affect the taste of your tea and may indicate that the kettle needs to be replaced. Rust can also potentially contaminate your water if it flakes off into your drink. It is best to avoid using a rusty tea kettle to ensure the quality of your tea and your health.
